Chladni figures-making sound visible
The Chladni figures are named after the German scientist Ernst Florens Friedrich Chladni (1756-1827).
Chladni excited the normal modes of thin metal plates covered with sand by stroking ...

Objective: Measurement of instantaneous velocity as a function of distance covered
In the case of uniform acceleration, the instantaneous velocity increases as the distance covered becomes greater. The constant of proportionality between ...

Objective: Record and evaluate motion with uniform acceleration on a roller track
When uniformly accelerated motion takes place the velocity at any instant is linearly proportional to the time, while the relationship between distance and ...

Objective: Investigate uni-dimensional collisions on an air track
One important consequence of Newton’s third law is the conservation of momentum in collisions between two bodies. One way of verifying this is to investigate collisions ...

Objective: Determine the acceleration of a falling object.
In free fall the distance fallen h is proportional to the square of the time t taken to fall that distance. The coefficient of that proportionality can be used to calculate the acceleration ...

Objective: Plotting the “parabolic” trajectories point by point
The motion of a ball that is thrown upward at an angle to the horizontal in the earth’s gravitational
field follows a parabolic curve whose height and width depend on the throwing ...

Objective: Investigate elastic and inelastic collisions between two objects on a plane
In any collision between two bodies, the colliding objects must obey the laws of conservation of energy and conservation of momentum. With the help of ...

Objective: Confirm the law of equal areas for central force motions (Kepler’s Second Law)
As an example of motion under the influence of a central force, the elliptical motion of a pendulum bob is recorded by the dust-marking method. This ...
